In order for me to count a song as a meme, it would have to fit one of these criteria: 1. The song was made for comedic purposes (Eg. The Fox by Ylvis) 2. The song was made as a normal song but became a joke (Eg. Dance Monkey by Tones and I) 3. The song has become a cliché for certain situations and has become a sort of theme for those situations (Eg. The Final Countdown) 4. The song has become the theme for a specific meme (Eg. Astronomia with Coffin Dance) 5. The song is a commonly used background song for scenes and montages (Eg. Ride of the Valkyries by Richard Wagner) There are some minor exceptions, but I hope this clears up some confusion.
